Low-Frequency Modulator Circuit

Published:2011/5/21 8:17:00 Author:Robert | Keyword: Low-Frequency, Modulator | From:SeekIC

This circuit is a amplitude modulator circuit. The T1 and T2 transistors are used to separate the modulator part. The low-frequency signal has the best value when the potentiometer RP1 is adjusted to about 500mV. The low-frequency then passes the isolation stage T3 which would output low-frequency modulation signals. The low-frequency amplitude is adjusted by the potentiometer RP2.
